ff t l Patented Dec. 10, 1929 UNITED STATES CHARLES H. GRUBB, OF BARABOO, WISCONSIN STANCHION Application filed April 18,

This invention relates to cow stanchions, the primary object of the invention being to provide means for closing or guarding the space between the members of the stanchion and frame in which they are supported to prevent cows from passing their heads between the stanchion and stanchion frame.

Another object of the invention is to provide an operating mechanism which will be easily operated, and one wherein the pivoted arms and links are normally held of dead center.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational view lillustrating a stanchion` constructed in accordance with the invention, showing the same in an open position.

Figure 2 is a view showing the stanchion in its closed position.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Referring to the drawing in detail, the reference character 5 designates the upper and lower stringere of the usual stanchion frame. These stringers are held in spaced relation by the uprights or standards 6 which also separate the stanchions proper.

Extending along the upper Stringer, and connected with the various stanchions, are

two rods 7 to which the link 8 is connected,

the link 8 being also connected with the upstanding extremity 9 of the movable section 10 of the stanchion so that movement of the rods 7 and link 8 will result in a relative l movement of the movable section 10 to close or op en the stanchion.

The stanchion also includes a stationary section 11 which is supported in the usual and well known manner.

The device forming the subject matter of SURE sfror 192s. serial No. 271,020.

this invention also embodies a pivoted arm 12 which is in the form 0f a pipe having pivotal connection with the rods 7, through thc link v13 that is adjustable along the rods 7 so that the throw of the rods 7 may be regulated.

This arm 12 is supported in such a way that when lever 12 is moved to open the stanchion, arm 12 assumes a position at an oblique angle with respect to one side of the stanchion, and standard to which it is pivotally connected, thereby guarding the space between the standard and'stanchion to prevent a cow from passing its head through this space on entering the stanchion.

Associatedwith each arm 12, is arm 14 pivotally connected to the standard on which the arm 12 is mounted, the arm 12 being relatively long, so that when the lever 12 has been moved to a position to open the stanclr ion, the arm 14 will extend laterally at an ob lique angle to guard the space between the opposite side of the stanchion and standard of the adjacent stanchion.

The arm 111 is supplied with a bolt 15 that acts as a pivot for the links 16 disposed on both sides of the arm, which'links connect with the arms 17 secured to the standard forming a part of the stanchion frame.

Links 18 connect with the arms 17, which links are connected with the arm 12 associated therewith, through the medium of the bolt 19. A bolt indicated at 2O extends. through the arms 17 and through securing blocks 21, the bolt 20 also passing through the standard of the stanchion frame so that a free pivotal movement of the arms 17 will be had.

As clearly shown by the drawing the ends of the arms 17 extend inwardly so that they will contactk with the links 16 and 18, the inturned extremities being indicated by the reference character 22. rIhe inturned ends 22 at one side of the standard on which the arms 17 are mounted, contact with the upper side edges of the links 16, while the inturned ends 22 at the Opposite side of the standard Contact with the under sides of the links 18 thereby restricting movement of the arms and links to prevent the arms and links from being moved on a direct line with the result that the connections between the links 16, links 18 and arms 17 will be partly broken allowing the easy operation of the stanchion.

It is to be understood that an arm such as shown and described is secured to each upright or standard of the stanchion frame and connects with the rods 7 through links v13 ofthe operating' mechanism to the en d that all of the stanchions of a row may be operated by moving the lever 12 at one end of the stanchion frame.

The usual latch for locking the stanchion in its closed position is indicated, by the ref'- erence character 23, and may be operated should it be desired to lock one of the stanchions and open the remaining stanchions.

From an observation oit' Figure 1, it will be obvious that Va cow entering the stanchion must place her head between the side members of the stanchion, the spaces between the side edges of the stanchion and uprights or standards being guarded.

I claim:

1. In combination with a stanchion and-the uprights between which the stanchion is po-V sitioned, downwardly extended guarding arms pivotally connected to the uprights, upstanding guarding arms pivotally connected to the uprights below the first mentioned arms, operating arms pivotally supported on the uprights and having inturned ends, links connected to the guarding armsI and having connection with the operating arms, said inturned ends of the operating arms adapted to engage the links to restrict movement of the guarding arms, and said guarding arms adapted to guard the spaces between the stanchions and uprights'.

2. In combination with a stanchion and the uprights between which the stanchion is positioned, guarding arms pivotally connected with the uprights, operating arms pivotally mounted on the uprights, links connecting the operating arms land guarding arms, and means at the ends of the operating arms for contacting with the links to restrict movement of the guarding arms.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
